Explanation
Security steering committees provide a forum for management to express its opinion and take ownership in the decision making process. Security awareness campaigns, security policies and procedures, and self- assessment exercises are all good but do not exemplify the taking of ownership by management.

Explanation
According to the Certified Information Security Manager (CISM) Study Guide, one of the primary responsibilities of an information security manager is to ensure that changes to systems and processes are managed in a secure and controlled manner. The change management procedure that is most likely to cause concern for an information security manager is when the development manager migrates programs into production without proper oversight or control. This can increase the risk of unauthorized changes being made to systems and data, and can also increase the risk of configuration errors or other issues that can negatively impact the security and availability of systems. To mitigate these risks, it is important for the information security manager to work closely with the development team to establish and enforce change management procedures that ensure that all changes are properly approved, tested, and implemented in a controlled manner.

The discovery of a Trojan installed on a system's administrator's laptop is highly significant since this may mean that privileged user accounts and passwords may have been compromised. The other choices, although important, do not pose as immediate or as critical a threat.
